Title: Low distortion shroud for turbine
Inventor: JIOMACAS CHRIS BASIL
IPC: F01D25/14
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide shroud segments so formed that thermal distortion is reduced to minimum, which distortion is generated by heat transmission from a heat gas flow passage to a shroud through a turbine, in regard to the shroud which surrounds the tip of a dynamic blade on a static blade of the turbine. SOLUTION: A flow passage shroud 22 is a plurality of channel shroud segments each formed of a front rail 24, a rear rail 26, and a flow passage portion 28 connecting them to each other along a radially innermost portion. Capacity has boundary which is determined by front and rear rails 24, 26, and the flow passage portion 28 other than both ends. The shroud does not have a side wall, accordingly. A relief is cut on each of free ends of the front and rear rails 24, 26. As a result, mechanical stress to be applied to a hook of a turbine casing is limited even when the front and rear rails 24, 26 are thermally introduced in an axial direction and bent. Thickness of front and rear rails 24, 26 is substantially equalized to that of the flow passage portion 28.
